Google PCA Ensure solution and operations reliability Practice Question
Exhibit
Refer to the exhibit.
{
"kind": "storage#bucket",
"id": "my-important-bucket",
"name": "my-important-bucket",
"retentionPolicy": {
"retentionPeriod": "2592000",
"effectiveTime": "2024-01-01T00:00:00Z",
"isLocked": true
},
"versioning": {
"enabled": true
}
}The exhibit shows a Cloud Storage bucket configuration. What does this configuration ensure?
⚠ Common exam trap
Test-takers frequently confuse retention policies with lifecycle management rules, mistakenly thinking retention policies automatically delete or transition objects, when in fact they only prevent deletion until the retention period expires.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Objects can only be permanently deleted after the retention period expires.
The exhibit shows a bucket configured with a retention policy. When a retention policy is set on a Cloud Storage bucket, objects cannot be deleted or overwritten until the retention period expires. This ensures that objects can only be permanently deleted after the retention period ends, which is exactly what option C describes.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Older versions of objects are automatically transferred to a different storage class.
Why it's wrong here
Object Versioning must be enabled for noncurrent versions to exist; without it, lifecycle rules acting on noncurrent versions have nothing to transition. Versioning plus a noncurrent-age transition rule is correct when retaining and tiering superseded object versions.
- ✗
Data is replicated to another region for disaster recovery.
Why it's wrong here
Cross-region replication requires dual-region or multi-region bucket placement; a single-region bucket with lifecycle rules replicates nothing. It is tempting because replication genuinely serves disaster recovery, and would be correct where the bucket's location setting spans two regions.
- ✓
Objects can only be permanently deleted after the retention period expires.
Why this is correct
A bucket retention policy with a set retention period locks each object until that period elapses, so deletion requests are refused beforehand. This directly enforces the configuration's guarantee that permanent deletion is possible only once the retention period expires.
- ✗
Objects older than 30 days will be automatically deleted.
Why it's wrong here
Lifecycle rules with an age condition and a Delete action remove objects after the specified days; the exhibit's rule instead specifies a storage-class transition, so nothing is deleted. Deletion rules are correct when the requirement is expiry rather than cost-tiering.
